props

Response data properties. Evaluates the current request as if it were an image request (req=img), but instead of returning the image, the server returns selected properties of the reply image.

req=props[,text|javascript|xml|{json[&id= *reqId*}]

reqId

Unique request identifier.

Requests that support JSONP response format lets you specify the name of the JS callback handler using the extended syntax of req= parameter:

req=...,json [&handler = reqHandler ]

<reqHandler> is the name of the JS handler that is present in the JSONP response. Only a-z, A-Z, and 0-9 characters are allowed. Optional. Default is s7jsonResponse.
